I have 6+ years of consulting under my belt, and have been involved in a wide
range of technical topics, both in development and operations. If you're
looking for lead-dev / CTO-like level of skills, I can deliver.

Over the years I developed a strong ability to get up and running on
new/existing projects very quickly. Also, having products (and paying clients)
myself means I understand what drives a business and can often find solutions
that were not envisioned by other members of the project.

My main interests right now

Streamlining deployment pipelines. Compared to the usual deployment tooling,
orchestration tools such as Kubernetes or Convox give you at least a 10x
velocity for deploying apps, for at least half of the cost.

Hosting high traffic websites, and finding every way to reduce hosting bills
with agressive caching (both HTTP and application-level), performance
improvement in the hosted apps (less time spent processing requests = less
servers needed), profiling and refactoring hot paths, and last but not least,
better usage of cloud providers.

Development of Rails5 apps. Also interested in Next.js and React.

I know how to deal with heavy or spiky trafficThose t2.medium instances are running 30 processes in total. Stop wasting your (expensive) resources.

Some examples of things I've done in the past

Revamping AWS infrastructure for a company offering a SaaS, reducing AWS bill
from $15k to $2.5k. And at the same time, getting them a nice platform and
continuous integration system to build, test, deploy, and monitor their
services.

Migrating large (and critical) RubyOnRails projects from Rails2.x/Ruby1.8 to
Rails4.x/Ruby2.x (and then Rails 5.x), adding a strong test suite and CI
pipeline to ensure the main features were working with the new stack as we went
over the numerous changes required to upgrade.

Setup of CI/CD systems.

Setup of infrastructure provisioning with Puppet.

Migrating applications to docker, and everything that goes with it.

Writing tests, both as blackbox tests against legacy systems to prepare for a
migration, and unit/integration/system tests.

Advising and implementing Single Sign On solutions.

ElasticSearch interactions (indexing, aggregations, reporting).

I'm preferably working remotely, but for larger projects I will generally
travel to meet your team at the beginning of the contract. I can also work on
site if you're based in the region of Rennes, France.
